Class Duels is a classroom revision quiz site. It is designed to work without student accounts, logins, names, email addresses or public posting.

Information entered by users

The public quiz pages do not ask students or teachers to enter personal information. Quiz choices, timer values and topic choices are processed in the browser so the quiz can run.

Local storage

Class Duels may save basic quiz preferences and local high-score information in the browser on the device being used. This information stays on that device and is not used to identify a student.

Analytics

Class Duels uses Clicky to understand basic website usage, such as which pages are visited and whether the site is working correctly. Clicky may process technical information such as IP address, browser, device type, referrer and pages viewed.

Third-party files

Some pages load JavaScript and CSS from jsDelivr for MathJax and syntax highlighting. These files help display maths notation and code examples correctly. When a browser requests these files, jsDelivr may receive standard technical request information such as IP address and browser details.
